Bachelor Party is an adult-themed video game for the Atari 2600 developed by Mystique. The game is a simplified version of Breakout where the "ball" is made to look like a nude man and the "bricks" are made to look like nude women and the man bounces back and forth horizontally rather than vertically.

An Adult Video Game was unheard of in the early days of console game. Regardless, Bachelor Party was one of those very few games that was regarded at that time as an Adult Video Game (or at least claimed to be one).
Bachelor Party is a simple straight-forward pong game but with a wild twist: the objective of the game is help ol'bachelor (read=ball) here get lucky with the ladies by "hitting" him with a dose Spanish Fly (read=paddle, and that's a lot of doses!), hopefully with your help, he'll "score" frequently. When each lady is "hit", the lady disappears until all 8-16 ladies are "subdued" and on to the next level. Looks like someone's gonna be busy tonight.
The bachelor has 4 lives to start and in order to survive (the night) he has to keep getting a regular dose of Spanish Fly (since without it...you know...) to keep the ladies (and him) happy.
The game consists of 2 player modes and 4 level modes: Games number 1 and 3 are one-player versions and 2 and 4 are two-player versions. In games 1 and 2 there are two rows of 4 women in each row. Games 3 and 4 are more difficult in that there are two rows of 8 women in each row, and they slowly advance during play (looks like the Spanish Fly is working!)
One last funny thing is that the bachelor appears to have three arms...*ahem*
